L = 3C ( Lacey sold three times as many calendars as Chris)
T = 5 + C (Talia sold 5 more calendars than Chris)
Answer:
(-84) and (-83).
Step-by-step explanation:
1) according to the condition 'two conscutive integers' means x and x+1;
2) according to the condition x+(x+1)=-167;
3) if to solve this equation, then
x= -84, it means the required integers are: (-84) and (-83).
Answer:
Period annuity is the answer.
Step-by-step explanation:
Period annuity or fixed period describes a financial product offered by insurance companies that, in return for an investment, provides fixed payments each month for a certain amount of time.
A period annuity pays income to the person for a specified period of time like ten years. The payments depend on the amount paid into the annuity and the length of the payout period.
Whereas, the lifetime annuity provides income for the remaining life of the person.
Therefore, period annuity or fixed period annuity is the answer.
Xy 14
x + y = -4
x + y = -4
x - x + y = -x - 4
y = -x - 4
xy = 14
x(-x - 4) = 14
x(-x) - x(4) = 14
-x² - 4x = 14
-x² - 4x - 14 = 0
-1(x²) - 1(4x) - 1(14) = 0
-1(x² + 4x + 14) = 0
-1 -1
x² + 4x + 14 = 0
x = -(4) ± √((4)² - 4(1)(14))
2(1)
x = -4 ± √(16 - 56)

x = -4 ± √(-40)

x = -4 ± 2i√(10)

x = -2 ± i√(10)
x + y = -4
-2 ± i√(10) + y = -4
- (-2 ± i√(10)) - (-2 ± i√(10))
y = -2 ± i√(10)
(x, y) = (-2 ± √(10), -2 ± √(10))
The two numbers that multiply to 14 and add up to -4 are -2 ± i√(10).
